A building automation system or BAS is a network of controlling and monitoring devices mainly responsible for the heating, ventilation, and air conditioning (HVAC) control system in large facilities and commercial buildings. Building automation systems are most commonly implemented in large facilities such as healthcare facilities, schools, universities, hotels, residential buildings, and data centers. A BAS network allows building operators to supervise and control the HVAC systems from a centralized location known as the Building Management System or BMS. VAV system, the air handling unit (AHU) and the VAV boxes are physically separated from each other, and each one has its own controller, also distanced from one another. However, for a VAV system to operate effectively, the VAV Boxes and the AHU have to talk to each other; in other words, they need to share information to properly adjust their setpoints based on zone heating or cooling demand.
Gas Turbine Components & Working Principle
Introduction
A gas turbine is a type of internal combustion engine that converts natural gas or other fuels into mechanical energy, which is then used to generate electricity or power machines.
Major Components of a Gas Turbine
- Compressor: Compresses the incoming air to a higher pressure.
- Combustion Chamber: Burns the compressed air and fuel to produce high-pressure, high-temperature gas.
- Turbine: Extracts energy from the high-pressure gas to drive the compressor and produce power.
- Exhaust System: Releases the used gas efficiently.
Working Principle
- Air is drawn into the compressor and compressed to a high pressure.
- The compressed air is mixed with fuel in the combustion chamber and ignited to generate high-temperature gas.
- This high-energy gas passes through the turbine, causing it to spin and produce mechanical energy.
- The mechanical energy can be used for electricity generation or other industrial processes.
